OIL-RETAINER.

' Application filed September 22, 1920. Serial No. 411,893.

T0012 whom it may con cern:

Be it known that we, ROGER W. HASTINGS and CLARK \V. PARKER, citizen of the United States, and residin at New. York, county of New York, and tate of New York, have invented a new and Improved Oil-Retainer,

catingoil from the receptacle which incloses the .drlving gears of such axle constructions.

ThlS invention consists in the details of construction illustrated in the accompanyingdrawing and pai'ticula-rly pointed out in the claims.-

In the drawing, Figure 1 is a longitudinal section of atractorv wheel hub and the ,drivin and su ortin mechanism there- {'1 D for. Fig. 2 is a central section of the oil retainer. I Fig. 3 is a perspective of the oil retainer.

Similar reference characters refer to like parts throughout the several views.

Fig. 1 shows an axle 1 and a casin 2 mounted thereon which embodies a cylin riwith theteeth-7 of theinternal gear ring 87 secured to the disk 9, which in turn 1s secured to the flange 10 of the hub 11 rotatably mounted on the outer end of the axle 1.

Secured to the casing 2 just around the axle and also to the part 3 of the casing just around the pinion is a dished plate 13 whose outer edge connects to the ring 14, the plate 13 and the ring 14 constituting a retainer for the lubricant which constantly keeps the teeth of the pinion and the gear ring and the bearings for the pinion and r the hub supplied with oil.

To prevent the oil from escaping along the shaft 6 an oil retainer is providedconsist- I ing of the pressed rings 15 and 16 and the packing ring 17 of felt or'other fibrous material between them. This oil retainer is held in position I by the bearing for the pinion. This mechanism in itself forms no part of the present invention.

Specification of Letters Patent.

Patented June 14, 1921,".

In Figs. 2 and 3 are shown the ,flange of the hub which is formed with a groove' 18 and. a sharp circumferential rib 1 9 and;

the ring 20 which is attached mal ring portion 14 of the oil receptacle and is provided with a notch 21.: Thering 20 extends around just out of contact with the portion} while a finger 22 of thin sheet metal pre'ss'e's' lightly against the rib 19,,being so'securedi to the ring 20 as to extend into the notch 212 Lubricant reaches the flange 10 of thehub of the hub of largest diameter and the ring] t 14: around a portion of smaller diameter in small amounts when the hub is turning slowly and most of it is wiped off the" inner edge of the ring. Of the remainder which passes the inner edge of the ring 20, the greater portion drips oil the edge 23 of the flange '10. The small amount which passes to the outside of the rib 19 is allscraped ofl by the finger 22 and runs down the finger into the oil receptaclee It will be understood that this finger ism preferably mounted at the lowest point in the ring 20.

Owing to the largest diameter of the hub being within the ring 20, the ring 14 of the oil receptacle can be freely removed, permitting the removal of the hub and the 25 and the nut 26 have been taken off. This is of great importance as it reduces .to a minimum the number of parts whichmust be disconnected to get at the hub bearings.

The details of this constructionmay be modified to meet the various requirements by those skilled in the art without departing from the spirit of our invention as set forth in the following claims.

We claim 1. An oil retainer. comprising an annular oil receptacle surrounding the driving mechanism of a tractor wheel Whose hub com- .parts connected thereto after the hub capf prises a circumferential rib, a. ring secured metal finger mounted on said ring and engaging-the outer side of said rib.

2.111 combination, a wheel hub having a circumferential .rib, an annularoil receptacle surrounding the hub, a ring secured to the inner side of one Wall of the receptacle concentric with the hub, and a metal finger mounted on said ring and engaging said rib.

3. In combination, an axle, a tractor wheel hub mounted thereon and having a portion of greatest diameter and a circumferential rib separated therefrom by a groove, an oil receptacle attached to the axle and comprising two annular parts connected at their outer edges and inclosing the por tion of the hub of greatest diameter and said rib, and an oil intercepting ring attached to the inner side 01? the outer part of the re- .ceptacie and of greater internal diameter than the diameter of said rib.

d. In combination, an axle, a tractor Wheel hub mounted thereon and having a portion of greatest dian'ieter and a circumferential rib separated therefrom by a groove, an oil receptacle attached to the axle and comprising two annular parts connected at their outer edges and inclosing the portion-of the hub of greatest diameter and said rib, an oil intercepting ring at tached to the inner side of the outer part of the receptacle and of greater internal dian'r eter than the diameter of said rib, said ring having a notch in itsinner edge, and a spring finger mounted in said notch and 611- gaging the rib on the hub to scrape off the oil thereon. r

5. In combination, a vehicle Wheel hub and a driving gear attached thereto, an'axie on which the hub is mounted, a circular oil receptacle attached to the axle and extending around said gear, the outer portion of said receptacle comprising a disk having acentral opening through which the hub extends a ring secured to the inside of said disk inalinement with the largest diameter of said huh, and means for engaging the hub between the disk and ring. v

G. in combination, a Wheel hub having a circumferential groove in the port-ion of greatest diameter to lea re a circumferential rib, a driving gear attached to the hub, an oil receptacle comprising circular disks having central apertures and formed with engaging flanges at their outer edges, the inner edge of the outer disk being positioned outside of the rib, a ring attached to the oil receptacle in a transverse plane passing through the portion of the hub of greatest diameter, and means to remove lubricating oil from said rib.
